目的调查皖北地区人居环境、工作环境及仓储环境中粉螨孳生情况及多样性。方法采用直接镜检法和水膜镜检法分离粉螨,并进行计数、鉴定及数据分析。结果 720份样本中,416份标本检获粉螨,总孳生率达57.78%;共检获粉螨41种,隶属7科20属,其中腐食酪螨为优势种。仓储环境孳生粉螨的物种数、丰富度指数及多样性指数较高,工作环境中相关指数较低;工作环境孳生粉螨的均匀度指数较高,人居环境相关指数较低。结论皖北地区粉螨种类较多,污染严重,其群落结构及多样性与生境条件有直接关系。
Objective To investigate the distribution and diversity of acaroid mites in living environment, working environment and storage environment in northern part of Anhui Province. Methods Direct microscopic examination and water microscopy were used to isolate acaroid mites, and their counting, identification and data analysis were performed. Results Among 720 samples, 416 samples were seized with the total breeding rate of 57.78%. A total of 41 species of acaroid mites were detected, belonging to 7 families and 20 genera. The species, abundance index and diversity index of acaroid mites propagated in storage environment were higher, while those in working environment were lower. The evenness index of acaroid mites in working environment was higher, and the index of human settlements environment was lower. Conclusion There are many species of acaroid mites in northern Anhui and their pollution is serious. The community structure and diversity are directly related to habitat conditions.
